The pieces of the N2CKH/R hub puzzle

I have been pretty busy hunting for the best deals on equipments for the system of late as can be seen below. It takes a lot of time and effort to find the hardware and more time to get it all working.

For the benefit all those that have never been down this road before (this is the biggest repeater project in my life) I have taken some snap shots of part of my collection of junk. I guess at present it can be referred to as my junk box until it is all put together and doing something useful. My wife certainly looks at it a big pile of junk.... beauty is in the eye of the beholder I guess.... hi hi


This photo shows the compact 6 foot Motorola repeater cabinet that will likely house the 2 meter repeater system. Also seen are a few cavities filters, UHF station master antenna and other things around it such as radio cabling, rack mount blowers and fans and more. I have two smaller Motorola 36 inch cabinets, one that will house the 6 meter repeaters satellite voting system.

GE brings good things to life and they certainly brought good things to amateur radio in the form of these surplus commercial land mobile radios for repeater making. The photo below shows the same Motorola repeater cabinet with the front door unlocked and removed currently filled with GE Master II/M radios for 10m, 6m, 2m, 220 and UHF use.

Also seen is a shared community tone panel for part of the UHF linking hub.

From this angle the tone panel and a GE rack mount amp and other items can be seen more clearly.

In this photo the full size GE Master Pro repeater cabinet that will house the UHF duplex linking hub equipment can be seen. The GE cabinet is a full size unit over 6 feet tall, with hinged locking doors front and back that takes full 26 in deep bays that I saved from the scrap heap recently.

At present I stored in it a GE repeater power supply at the bottom, I have four of these units, they are great buys.

On top of the GE power supply are two remote controllable Marway Power Systems rack mount switched/un-switched cirtcuit breaker power distribution panels that interface directly with APC UPS units. With the APC 4000 UPS units and the Marway switches we will have full emergency back up power and the ability to programmatically shutdown un-needed resources (a.k.a. Bells and Whistles) as the batteries drain both automated and via control operator DTMF signalling.

There are also Motorola, dbProducts amd Wacom duplexers, passband filters, pass/reject filters and circulators for all bands and Motorola Mitrek low band and UHF linking radios and more junk not seen in the photos.

In this photo shows some small dbProducts UHF cavities and another GE rack mount repeater amplifier and other items.

A photo that I must take is of all the manuals that I have been acquiring on the GE, Motorola and other equipments, it is quite impressive and a bit intimidating, piled one on top the other it would probably come close to a full 3 feet tall or more ! I just acquired a ton of additional manuals for the library that are not specific for any equipments that I currently have that would bring the pile to well over 6 feet !!

I have also been busy collecting test equipments to include a Motorola R-2001D/HS communications service monitor and many other pieces that are needed for the effort.
